White Fused Alumina
1)White Fused Alumina is made by first grade alumina as raw material, smelting in electric arc furnace at high temperature.
2)Wilead brand White Fused Alumina:corundum crystals is good, volume density, high purity, good temperature, acid alkali corrosion is strong.
3)White Fused Alumina hardness is higher but toughness lower compared with Brown Aluminum Oxide.
4)White Fused Alumina is characterized by high purity, excellent self-sharpening, efficient grinding efficiency, and low frictional heat.
